To all whom it may concern.-

Be it known that We, JAMES F. WEST and WILLIAM O. COWLEY, citizens of the United States, residing at Wichita, in the county of Sedgwick and State of Kansas, have invented certain new and useful Improvements in Mixing-Machines, of which the following is a specification.

Our invention relates to certain new and useful improvements in mixing-machines for concrete or the like andthe object of the invention is to provide a machine of this type which is composed of comparatively few and simple parts that will be durable in construction and which may be run easily and effectively to thoroughly mix the required ingredients, first in a dry stateand then wet, if desired, and finally discharge them in a continuous stream at the outer end of the machine.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description and accompanying drawings, in Which Figure 1 is a transverse sectional view of Fig. 2 is a side elevation thereof with parts broken away. Fig. 3 is an end elevation from one end of the machine. Fig. 4 is a similar view of the upper portion of the machine looking 7 at the opposite-side. Figs. 5 and 6 are detail views of one of the feeding-rolls.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

Our improved machine'comprises a supportin -framework 1, which may be of any 5 construction and which supports the desire hoppers 2 and the other parts of the machine. The hoppers 2 are provided with a common discharge-chute 3, and the passage of the ingredients to said chute from the discharge ends of the hoppers is controlled by means of corrugated rolls 4, preferably cared together and mounted on shafts 5. nderneath the discharge-chute 3 is located a sluice 6, which is inclined, as shown in Fig. 1, andis provided on its upper surface with a series of steps 7. The sluice 6 is mounted at its upper end upon a crank-shaft 8 and is pivotally held 'or supported at its lower end 1n hangers 9. Underneath the discharge end discharge end of the sluice 6 and preferably provided at one side with a flange 11 to properly direct the materials from the sluice into the mixing-drum. Within the mixing-drum is j ournaled a longitudinally-extending shaft 12, provided with .a series of mixing-shovels 13, that are oblique to the axis of the shaft, so that as the shaft is turned the ingredients will be conveyed gradually from the mixingdrum to the discharge end thereof while they are being mixed.

The mixing-shaft 12 may be driven by any suitable power-for instance, by means of a crank-handle 14and said shaft is provided with a sprocket 15, connected by sprocketchain 16 to a similar sprocket 17 on the crank-shaft 8. On the shaft 12 is another sprocket 18, connected by a chain 19 to a sprocket 20 on one of the shafts 5. The shafts 5 are geared together, preferably at opposite sides of the machine, as illustrated in Fig. 4, by means of spur-gears 21 and 22, one of Which is preferably larger than the other and which are proportioned in size according to the ingredients desired to be fed from the I butmay be used for mixingpurposes gener ally, and where certain pro ortions are to be accurately obtained and t oroughly mixed the wheels 21 and 22 will be changed in diam eteraccordingly, said wheels being preferably provided in pairs and properly proportioned to each other, according to the particular use intended.

As the ingredients are fed from the hoppers, the shaft 12 being actuated as above described, the ingredients'will fall upon the sluice 6 at its upper end, and as said sluice is shaken or vibrated by means of the crankshaft 8 the ingredients will be thoroughly mixed in a dry state before passing downwardly off the lower end of the sluice into the vided with suitable orifices for the pro er distribution of the water at said points. he pipe 23 is preferably provided with a screwthreaded end 24 or is similarly formed-for the convenient attachment of a hose or the like. As the ingredients are fed into the receiving end of the mixing-drum in their thoroughly dry-mixed condition the rotating shaft 12,

. with its shovels 13, will cause a thorough mixing of the materials in a wet condition and will at the same time gradually convey the mixed materials to andout of the discharge end of the machine, as indicated by the arrows in Fig. 2. 1

tion with the accompanying drawings, it' will be seen that we have provided a mixing-machine for concrete, mortar, or similar material which will first thoroughly effect a commingling of the ingredients by the vibrating sluice 6 and then will also effectively mix the materials after they have been sprayed by the action of the mixing devices in the mixing-drum 10 and finally discharge the same in their roper condition. It is to be noted that t e machine is light in structure and yet durable in construction and that it may be easily operated. It is further to be noted that the ingredients fed from the hoppers may be variously rop ortioned by changing the diameters of tl ie Wheels 21 and 22, as before set forth. i

From the foregoing description, in connec-v Having thus described the invention, what is claimed as new is A mixing-machine of the character described comprising a supporting-framework,

hoppers mounted thereon, corrugated rolls controlling the discharge ends of. said hoppers, gearing arranged to operate said rolls 2 of said .sluice is suspended, a mixing-drum having a feed-opening underneath the lower end of said sluice, a s ray-pi e mounted in the framework, provi ed wit jets designed to direct water or steam into the feed-opening ofthe mixing-drum and said pipe arranged for attachment to a supply-hose or the like, a mixing-shaft in said drum, conveying or mixing shovels mounted on said shaft, means for actuating said shaft, operative connections between said shaft and the crankshaft, and other connections between said shaft and one of the shafts of said corrugated JAMES F.
